It would make more sense to add pegmgf to igf. This would give you the greatest gains for sure. Most of gh's mechanism for growth is through it's ability to stimulate igf production.
I was just asking in general, for later down the road. I am going to add IGF-1 and run Grunt76's protocol, but It will probably be a ways down the road before I add anything else. I am currently on my 1st cycle and I think that IGF-1 will be a good addition, I plan on running it long term.
